--- Comment #8 from Julien Durillon julien.durillon@gmail.com 2011-02-13 11:23:56 PST --- Created an attachment (id=43323) --> (https://bugs.freedesktop.org/attachment.cgi?id=43323) gdb output when producing the bug

I experienced the same problem, and I ran gnome-shell through gdb. So Here is the debug output (fortunately, I even have the lines).

Hoping this helps,
